Three right-arrows, or one right-arrow "times 3" — the first loop.
Do this together
The star is three squares away. Tap the right arrow once, then tap the "×3" button and watch the little number appear on the step — that means "do this three times". Press Go.
Tap right once, tap ×3, then Go.
Grown-up tip
"Do it three times" is a loop — computers love loops. Try it with claps: "Clap, times three!"
